Dark, gritty and grainy, and very well done. I think it's great. Is the poor thing floating? My only gripe is that black spot on the right hand side - I'd have been sorely tempted to have cloned it out.
I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Kind of a brave rendition of a Ladybug - lose the colour, make it look a little ugly, show another side.
Critical stuff: I'm not a fan of your conversion - I can see some residual blue lines; I'm not sure why are there but I am sure that (IMHO) they don't work.
Overall: I like your vision but I think the execution leaves a lot to be desired.
